Bill Gates: Trump asked me the difference between HIV and HPV

Microsoft founder Bill Gates has been talking about his surreal encounters with President Donald Trump again, and this time he's revealed some worrying details about the president's lack of medical savvy.

Gates, who met Mr Trump again a year ago in the White House, also revealed that he had twice asked him the difference between HIV and HPV.

Mr Gates said last month that Mr Trump was "super interested" in the idea of a universal flu vaccine.

According to footage of the meeting broadcast by MSNBC on Thursday, Gates said Trump knew a "scary" amount about his daughter's appearance. Gates's comment: "It was actually kind of scary how much he knew about my daughters's appearance". "Melinda [Gates' wife] did not like that too well".

"Both times he wondered whether there was a difference between HPV and HIV", Gates said, "and I was able to explain those are rarely confused with each other".

Gates spoke about meeting Trump twice, once in 2016 and once in 2017. Gates then advised Trump to champion science and innovation.

Among other anecdotes, Gates is seen telling an audience about how, in both of his meetings with Trump, the president asked if there's a difference between HIV and HPV.

"I'd never met Donald Trump before he was elected", begins Gates, "there was a thing during the election where he and I were at the same place, and I avoided him".

The Bill & Melinda Gates Foundation has donated millions to public health and development initiatives.

Human papilloma virus (HPV) is the name for a group of viruses that affect your skin and the moist membranes lining your body, while HIV (human immunodeficiency virus) is a virus that damages the cells in your immune system and weakens your ability to fight everyday infections and disease. It is the virus that can lead to acquired immunodeficiency syndrome or AIDS if not treated. HPV is a different virus than HIV and HSV (herpes).

"I didn't know the third-party form was always expected". Gates' 22-year-old daughter Jennifer, an award-winning equestrian, had taken part at an event organized by Trump in Florida. In both meetings, he asked Gates if vaccines were good or bad, and Gates told him no.
